Subsequent 37 Stripped Screws

I have a Subsequent 37 that I need to replace the LHC on. The pitch bend wheel is acting erratically, modulating the pitch without being touched.

I preciously replaced it due to cosmetic damage to the paint, naively using isopropyl alcohol to clean it.
I happened to strip some screws on the side and the underneath. Where can I find the appropriate screws for the sides and underneath and how could I go about safely removing said screws?

Thank you!
